I Application filed June 3, 1916. Serial No. 101,448.

y,To all whom t may concern.'

dent of the city of NewYork, borough of Manhattan, in thecounty andState of New York, have invented a new and Improved Insole, of which thefollowing is a full, clear, and exact description.

Myinvention is an improvement in the class of insoles which areparticularly designed and adapted for use in rubber boots and compriseleather and sheet metal layers suitably secured together.

The improvement is hereinafter described in detail and illustrated inthe accompanying drawing, in which:

Figure l is a plan View of the insole with part broken out; Fig. 2.is alongitudinal central section of the same on the line 2--2 of Fig. 1;and'Fig. 3 is a cross section of the same on the line 3-3 of Fig. 1.

rlhe insole in its general construction consists of a bottom layer y10and a top layer 11, both made of leather' or a similar flexible materialwith a flexible sheet metal layer 12 interposed between the said layers10 and 11. The edge of the intermediate sheet metal layer 12 terminatesadistance from the edges of the bottom 'and top layers 10 and 11, andthesaid layers '10 and 11 are fastened together along the margin bystitches 13 so asto securelyhold the intermediate layer i12 in positionbetween the bottom and and waterproof cement 14 so as to prevent wateror moisture from passing between the layers and to prevent an electriccurrent from reaching the metallic intermediate layer 12. rllhe layers10, 11 and 12 follow the contour of the inner sole of a rubber boot, andthe layers are provided with upturnedflanges 15 at the instep of thefoot to protectthis portion of the-foot against nails and sharp objectsand to hold the foot from slipping sidewise and lengthwise. At

The edges of 'the' the instep use is made of padding pieces 16 and' 17overlying one the Aother and interposed between the top layer 11 and theintermediate layer 12 so as to form an arch support to sustain the arch.The size of the padding 17 is slightly in excess of the' padding 16 andthe margin thereof is fastened by transverse stitohes 18 to theuppermost layer 11 so as to hold the padding in place. llt will benoticed that by the arrangement described, nails or other sharp objectsare prevented from passing through the insole into the Wearers foot, andthe latter is held against sidewise movement and supports theJ archthusenabling a fireman or other wearer to obtain a firm foothold on therungs of a ladder when ascending or descending the same.

Heel and toe pads 20` and 21 are pasted orotherwise attached to the rearand front portions of the uppermost layer 11, and the said pads 20 and21 are preferably made of felt or other soft material so as to provide asoft rest for the corresponding porratentea nee. la, raie.

tions of thewearers foot to render walking v easy and comfortable.

It is expressly understoodythat the sheet metal layer12 is madesufficiently thin to readily flex with the other layers 10 and 11.

Having thus described my invention, I claim as new and desire' to secureby Letters Patent:

An insole comprising two layers of leather, a sheet metal layerinterposed between' the first named layers and "having its edgesterminating short of the edges thereof whereby the margins of the samemay be secured together, all of said layers having opposite laterallyprojecting and upturned flanges at the arch portions of the insole,superposed' padding elements arranged 'in the instep and between one ofsaid leather layers and said metallic layer and an elec l froierasNATHANPHILLrPs.
